@azure/storage-blob 如何从 Azuree 获取 uploadStream 图像 url 的结果答案

【发布时间】：2021-09-17 12:45:54
【问题描述】：

我正在将一个流上传到 azure blob 容器，它可以很好地上传到容器，但我不知道如何获取图像创建的 url，因此我可以将它返回到我的初始调用并在我的用户界面。

我可以取回请求 ID，这是否允许我从那里发出请求并获取图像 URL，我是否需要另一个请求，如果需要，我将如何编写它？

提前谢谢

我有以下

import formidable from 'formidable';
let streamifier = require('streamifier');
const fs = require('fs');
const os = require('os');

const {
  BlobServiceClient,
  StorageSharedKeyCredential,
  newPipeline
} = require('@azure/storage-blob');

const containerName1 = 'images';
const ONE_MEGABYTE = 1024 * 1024;
const uploadOptions = { bufferSize: 4 * ONE_MEGABYTE, maxBuffers: 20 };

const sharedKeyCredential = new StorageSharedKeyCredential(
  process.env.AZURE_STORAGE_ACCOUNT_NAME,
  process.env.AZURE_STORAGE_ACCOUNT_ACCESS_KEY
);
const pipeline = newPipeline(sharedKeyCredential);

const blobServiceClient = new BlobServiceClient(
  `https://${process.env.AZURE_STORAGE_ACCOUNT_NAME}.blob.core.windows.net`,
  pipeline
);

// first we need to disable the default body parser
export const config = {
  api: {
    bodyParser: false
  }
};

export default async function image(req, res) {
  try {
    const form = new formidable.IncomingForm();
    form.uploadDir = os.tmpdir();
    form.keepExtensions = true;
    form.parse(req, async (err, fields, files) => {
      var oldPath = files.image.path;
      var rawData = fs.readFileSync(oldPath);

      const buffer = rawData;

      const stream = streamifier.createReadStream(buffer);

      const containerClient = blobServiceClient.getContainerClient(
        containerName1
      );
      const blockBlobClient = containerClient.getBlockBlobClient(
        files.image.name
      );

      const result = await blockBlobClient.uploadStream(
        stream,
        uploadOptions.bufferSize,
        uploadOptions.maxBuffers,
        { blobHTTPHeaders: { blobContentType: 'image/jpeg' } }
      );

      console.log('result >>>>', result);
      // HERE I AM TRYING TO GET THE IMAGE URL, BUT IT JUST GIVES ME A OBJECT WITH REQUEST 
      // ID AND SUCH

      res.status(200).send({ message: 'File Uploaded' });
    });
  } catch (error) {
    console.error(error);
    res.status(error.requestResult.statusCode).send(error.message);
  }
}

【解决方案1】：

如果您只对获取 blob URL 感兴趣，则无需执行任何特殊操作。 BlockBlobClient 有一个名为 url 的属性，它将为您提供 blob 的 URL。

您的代码可以很简单：

res.status(200).send({ message: 'File Uploaded', url: blockBlobClient.url });
